Schneider Electric 140DAO84000 Discrete Output Module

Product Overview

The Schneider Electric 140DAO84000 delivers high-density AC discrete outputs for precise industrial device control.
Moreover, this module belongs to the Modicon Quantum series and supports demanding automation environments with stable electrical performance.
Additionally, the 140DAO84000 enables accurate switching control while maintaining isolation between outputs and field devices.
Therefore, system designers deploy this module to manage multiple actuators with consistent response characteristics.

Performance and Control Characteristics

First, the 140DAO84000 provides forty isolated discrete AC outputs for large-scale output control applications.
Next, each output supports nominal voltages between 22 and 283 VAC, ensuring compatibility with common industrial loads.
Furthermore, the module handles surge currents effectively, protecting outputs during transient electrical conditions.
Consequently, connected devices operate reliably during frequent switching cycles and load variations.

Electrical Design and Diagnostics

Notably, Schneider Electric integrates LED indicators to simplify real-time status monitoring and fault diagnostics.
In addition, green LEDs display bus activity and individual output states for rapid visual confirmation.
Meanwhile, a red LED immediately alerts operators to external fault conditions, reducing troubleshooting time.
As a result, maintenance teams improve system uptime through faster fault identification and corrective action.

Mechanical Construction and Installation

Likewise, the 140DAO84000 features a robust industrial housing suitable for rack-mounted Modicon Quantum systems.
Additionally, the compact form factor optimizes cabinet space while supporting high channel density configurations.
Meanwhile, the moderate module weight simplifies installation and replacement during system upgrades or maintenance.
Therefore, control panels remain organized while supporting scalable output expansion requirements.
